Display for rain tank - Please help

[pinie_pinie]

Hi Dani,

Super, super ... !!!
The display works as planned. When my control is completely installed I present a brief description.
One last question on this topic: The display on my phone (app) is not
possible? But is not absolutely necessary.
Thanks for everything! In the complex is a screenshot of the 50%.

See you soon Thoralf

In your phone, you can use a browser. But not that widget is not show on phone Apps.

Cheers
Dani

When you write up your system description, please let us know what sensors you are using in the tank.  I would like to have something similar for my sump pump to show normal levels and then alert if over that.  I saw some ineteresting usues of distance measuring using ultrasonic sensor with a ping pong ball in a pipe :-)  I was planning to do a couple float switches.

If you look at the schema of Thoralf in the previous page, he use only Cupper insulated cable with some screws at the level he needs. It's the conductivity of the water that make GPIO sensor of raspberry to be activate or not. Very cheeper solution.

Cheers
Dani

Hi,

the pipe I have poured with plastic. So that everything is watertight. The advantage: It has no moving parts in the water. My donor I have already 2 years in use. A relay board before Raspberry is ideal, then has to clean level at the input of the GPIO port. Perhaps the resistors at the input of the relay card must be adapted to the conductivity of the Waser is adjusted precisely.
